  • Publication number: 20080306625
    Abstract: A dual-phase virtual metrology method is disclosed for considering both promptness and accuracy by generating dual-phase virtual metrology (VM) values, wherein a Phase-I conjecture step emphasizes promptness by immediately calculating the Phase-I virtual metrology value (VMI) of a workpiece once the entire process data of the workpiece are completely collected; and a Phase-II conjecture step intensifies accuracy, which does not re-calculate the Phase-II virtual metrology values (VMII) of all the workpieces in the cassette until an actual metrology value (required for tuning or re-training purposes) of a selected workpiece in the same cassette is collected. Besides, the accompanying reliance index (RI) and global similarity index (GSI) of each VMI and VMII are also generated.

  • Patent number: 7457236
    Abstract: A method for providing an application cluster service (APCS) with fault-detection and failure-recovery capabilities. This method is composed of the steps of nodes clustering, invoking and detecting applications, fault-recovery of applications, detection of nodes, and node replacement. This method is applicable in a clustered environment to detect if a slave node is failed by sending a heartbeat periodically from a master node; and to detect if the master node still exists by checking if the master node stops sending the heartbeat (i.e. the master node may be failed).

  • Publication number: 20070282767
    Abstract: A method for evaluating reliance level of a virtual metrology system is disclosed. In this method, a reliance index (RI) and a RI threshold value are calculated by analyzing the process data of production equipment, thereby determining if the virtual metrology result is reliable. Besides, in this method, a global similarity index (GSI) and individual similarity indexes (ISI) are also provided for defining the degree of similarity between the current set of process data and all of the sets of historical process data used for establishing the conjecture model, thereby assisting the RI in gauging the degree of reliance and locating the key parameter(s) that cause major deviation.

  • Patent number: 7003367
    Abstract: An equipment management method for managing semiconductor equipment via an equipment manager. In the equipment management method, production scenario rules and equipment behavior rules are first defined respectively in a production scenario database of a configuration controller and an equipment behavior database of an equipment driver. Them, a command is received from a manufacturing execution system (MES), and is converted into a production process scenario by looking up the corresponding production scenario rule in the production scenario database. Thereafter, the production process scenario is converted into a GEI (generic equipment interface) message with a GEI message specification, and the GEI message is transmitted to the equipment driver. Then, the GEI message is converted into equipment communication messages regulated by an equipment communication protocol by looking up the corresponding equipment behavior rule in the equipment behavior database.
